In a typical mechatronic manufacturing functional test setup, actual load simulations are usually done by connecting the DUT outputs to power or ground in order to establish either a high or low side driver. Each output is connected with different load and the test will either be sequential or concurrent. At lower power levels, these can usually be managed with general purpose switches. However, when it comes to higher power levels of currents more than 5 amps, such switching and loading might pose a greater challenge. Furthermore, critically in the manufacturing line, the tradeoff between cost and test time would have a great influence on the test strategy.This paper will present some key points to design a cost effective high power switching and load management solution.

The process of manufacturing and qualifying IC's consists of many steps while Temperature forcing systems play a crucial role in the final testing process. These environmental tests assure quality and reliability by stressing the device on one hand as well as helping to characterize and validate it on the other hand (making sure manufacturing outcome meets the design requirements). At later stages the temperature testing can support failure analysis effort and root cause analysis. AS common practice we are dealing with few different kinds of temperature forcing systems: Chambers, Thermal Stream systems and Direct Thermal Head systems. In this article I would like to focus on the practical aspects of utilizing Thermal Stream systems and Direct Thermal Head systems.
